Sounds good so far! A big yes on the Extrusion frame! A bit more expensive but well worth the money, and the fab is easier than most. Are you set on Servos, because I mentioned on a previous thread, Automation Direct just came out with a Stepper combo that is hard to pass up on! All new stuff, with up to 20' of wire (Driver, Motors, Power Supply all configured together and delivered in a few days to the house, all brand new with warrenty...can't beat it).
Gotta ask, where in W. New York. I am in Fla now, but grew up in Alden. Good luck, ask if you need a hand or have any questions.
